Wren Chambers was on the train that stopped at Huntingdon and first became aware that something was amiss when a man bolted down the carriage with a bloody arm, saying "they've got a knife, run".

Another witness, Wren Chambers, said one person had been stabbed in the arm and bolted down the train to alert others - while another shouted "someone's got a knife".

Both novel and film would be set in Cape Cod, Mass., and there would be a mysterious woman named Wren, which is where the supernatural element would come in.

Wren has cerebral palsy, affecting her speech, all four of her limbs and her posture, meaning she needs help with everyday activities.

It’s a hellishly impressive performance by the young actor Jonah Wren Phillips, who does things with knives and teeth and windows and cats that will haunt your brain.
